T7660A/T7660B Space Temperature Sensor - Honeywell W180 User Manual

W180 ZONE CONTROL SYSTEM

T7660A/T7660B SPACE TEMPERATURE SENSOR

NOTES:
1. All wiring must conform to local codes, ordinances,
and regulations.
2. Do not run space sensor wiring in the same conduit
with ac wires.
3. The maximum distance between the space sensor
and the controller is 300 ft [91m] using 18 AWG
thermostat wire. To reduce noise on the sensor wires,
use shielded cable with the shield connected to
ground on the controller only.
4. Mount the space sensor on an inside wall approxi-
mately 54 in. [1372 mm] from the floor (or where
specified) where it is exposed to the average space
temperature.
5. Do not mount the space sensor on an outside wall or
a wall containing water pipes or air ducts near the
space sensor.
6. Avoid locations that are exposed to discharge air
from registers or radiation from lights, appliances, or
the sun.
Install and wire T7660A/T7660B Space Temperature
Sensors as follows:
1. Mount the space sensor mounting plate on a wall,
mullion (1-7/8 in. [48 mm] wide minimum), or electrical
box (Fig. 39 and Table 10).
